Well, it is not THAT easy. If you want resilience/availability, you'll need RAID. Now what do you put ontop of the RAID when you need to slice it? Put a disklabel/partition on top of it and stick with a static setup or use LVM which can span multiple RAIDs (and types) supports snapshotting etc. . Depending on your needs and usage you will end up with LVM in the end. If you want encryption, you'll need a crypto layer (or you put it in the FS alongside volume slicing). Partitions underaneath the RAID, not necessary if the RAID implementation can subslice physical devices and arrange for different levels on the same disk. Except unfortunately, when you need a bootloader. I don't see any alternative which would be KISS enough, except merging the layers to avoid collissions due to stacking order etc. . Simple usage and debugging for the user, but the actual single merged layer would be anything but KISS.
